The owner also needs to make arrangements to inspect the valves during the exercise. The owner will contact DSOD to witness the exercise. The large trees in the outflow channel need to be removed or trimmed to allow unobstructed flow (Photo 3). It appeared that no vegetation control has been practiced for many years in this area. All valves used for emergency drawdown should be cycled annually by the owner and in DSOD's presence every three years. In emergency, water can also be released through the Seepage The usual seepage along both groins has not changed. The left abutment has drains at different elevations. As in the past, Drain #1 and Drain #5 indicated some flow, and the others were dry. Drain #1 indicated a flow rate of approximately 1gpm, and Drain#5 indicated a flow rate of approximately 0.2gpm. The flows are considered normal. All these abutment drain flows and natural spring flows are collected at the toe of the left abutment and exit through the drainage channel. The right abutment seepage and the piezometer house road drain indicated a combined flow rate of around 20gpm, which is normal. Water flows from the drains were clear and free of sediment. Instr. The most recent instrumentation data submitted to DSOD by a letter dated July 31, 2105 extends through December, 2014. The instrumentation consists of open well (Type 1), hydraulic (Type II), and vibrating wire piezometers, survey monuments, settlement devices, and drain measurement devices. Survey Monuments and Settlement Devices: The dam has twenty one survey monuments along the crest and on the downstream slope. As in the past, the historically high settlement of around 1foot was observed on the crest monuments located near the highest section of the dam. The freeboard lost is not a concern because there was a camber of close to 3 feet. No noticeable changes were observed in the annual settlement of the monuments. Horizontal movements in the monuments were also acceptable; no significant changes were observed in the last 10 years. Piezometers: Vibrating wire and Type I piezometers indicated a very minimal fluctuations. Some of the Type II piezometer readings fluctuated within acceptable ranges. It appeared that the piezometers near the right abutment were influenced by natural springs. The readings in the upstream slope piezometers 28, 32, and 35 recently started to fluctuate noticeably (after 2011 ); the owner needs to investigate the possibility of any external water source. Overall, the water levels in the piezometers were below the design phreatic water surface and are acceptable. Seepage Measurements: The groin drains, and piezometer house and road drains showed normal readings. The seepage measurements continued to follow the historical trend. The recorded flow rates are considered normal at this time. Based on the submitted data, the dam is performing satisfactorily. Additional instrumentation is not judged necessary at this time.

As in the past, Drain #1 and Drain #5 indicated some flow, and the others were dry. Drain #1 indicated a flow rate of approximately 0.5gpm, and Drain#5 indicated a flow rate of approximately 0.1 gpm. The flows are considered normal. All these abutment drain flows and natural spring flows are collected at the toe of the left abutment and exit through the drainage channel. No notable flows were observed from the right abutment seepage and the piezometer house road drain. The north road drain indicated a flow rate of approximately 1gpm.

The most recent instrumentation data submitted to DSOD (dated June 23, 2014) extends through December, 2013. The instrumentation consists of open well (Type 1), hydraulic (Type II), and vibrating wire piezometers, survey monuments, settlement devices, and drain measurement devices. Survey Monuments and Settlement Devices: The dam has twenty one survey monuments along the crest and on the downstream slope. As in the past, Monument 10, which is located on the dam crest at the highest section of the dam, indicated historically high settlement of about 1.1 feet. The freeboard lost is not a concern because there was a camber of close to 3 feet. Overall, the settlement monuments indicated normal readings. The observed annual settlements are negligible. Overall no noticeable settlement was observed in the last 10 years. Also, no noticeable horizontal movement was observed annually for in the last 10 years. Piezometers: Type I piezometers indicated acceptable fluctuations. As in the past, Piezometer 1 showed the most fluctuation. This piezometer is located at the top of the downstream left abutment contact. It should be noted that natural springs also feed water to this area. Since many of the Type II piezometers continued to indicate erratic readings, the owner decided to remove the erratic ones from monitoring. This is acceptable. The vibrating wire piezometer readings remained steady with very minimal fluctuations. They are all located on the downstream slope of the dam. The water levels in the piezometers were below the design phreatic water surface. The piezometer readings are acceptable.

The valve and the operator appeared to be satisfactory. The valve has not been fully exercised in the presence of DSOD for many years (more than 5 years). It was partially exercised in 2006. All valves used in the emergency drawdown should be cycled annually by the owner and in DSOD's presence every three years. In emergency, water can also be released through the water distribution line. Seepage As usual, historical seepage was observed along both groins. The left abutment has six (6) drains at different elevations. Drain #1 and Drain #5 indicated some flow, and other drains remained dry as usual. Drain #1 indicated a flow rate of approximately 0.5gpm, and Drain#5 indicated a flow rate of approximately 0.1 gpm. All these abutment drain flows and natural spring flows are collected at the toe of the left abutment (south drain, see Photo 2 for the outfall location) indicating a flow rate of approximately 20 gpm. The right abutment seepage was estimated as 3gpm. The north road drain indicated a flow rate of approximately 5gpm, and the piezometer house road drain indicated a negligible flow. The observed flow rates are considered normal. Water flows from all the drains were clear and free of sediments. Instr. The most recent instrumentation data submitted to DSOD (dated June 7, 2013) extends through December, 2012. The instrumentation consists of open well (Type 1), hydraulic (Type II), and vibrating wire piezometers, survey monuments, settlement devices, and drain measurement devices. Survey Monuments and Settlement Devices: The dam has twenty one survey monuments along the crest and on the downstream slope. As in the past, Monument 10, which is located on the dam crest at the highest section of the dam, indicated a maximum historical settlement of 1.1 feet. The freeboard lost is not a concern because there was a camber close to 3 feet. The rest of the settlement monuments indicated normal readings. The annual settlements in the survey monuments are negligible. Overall the settlement rate remains close to 0.1 foot over the last 20 years. The maximum horizontal displacement of 0.25 foot towards the downstream occurred near the highest section of the dam. The annual horizontal displacement is less than 0.06 foot. The rate of horizontal displacement over the last 20 years is very minimal, and it is not a concern for now. The two settlement devices at Station 11 +60 and Station 14+80 were not read, and they appeared to be out of service. This is acceptable for now. Piezometers: Type I piezometers generally indicated minimal fluctuations with the reservoir level, except for Piezometer 1, which showed a noticeable fluctuation with the reservoir level. This piezometer is located at the top of the left groin. Many Type II piezomaters indicated erratic DWR 1261 (rev. 10/09) Sheet 2 of 4 10-21 James Turner Date of lnspection _ _ _ _7_/_2_1_/2_0_1_4_ _ __ Observations and Comments readings. As stated in the past inspections, the owner should evaluate the usefulness of the Type II piezometers. The piezometers that function properly did not show any abnormal readings. They followed the historical trend. Vibrating wire piezometers hardly showed any variations, and some of them indicated dry condition. They are all located on the downstream slope of the dam. The water levels in the piezometers were below the design phreatic water surface.

Observations and Comments Dam The rock covered upstream slope appeared to be in good condition with no signs of instability (Photo 1). The riprap appeared to be old but still intact; no raveling was noted as the reservoir level was lower than the usual levels. The paved dam crest and the downstream slope of the dam (Photo 2) also appeared to be in satisfactory condition with no cracks or evidence of any slope instability. No significant rodent activities were observed. The vegetation control on the downstream slope face of the dam was good; however, as in the previous inspections, minor bushes/tule growth was noted along the abutment contacts where seepage is observed historically. Vegetation on the seepage areas should be periodically controlled to allow a thorough inspection for seepage. Spillway The spillway approach, concrete-lined channel, chute, and downstream discharge area (Photo 3) appeared to be in satisfactory condition. They were clear and unobstructed. The spillway drains and weep holes were clear and no flow was noted. The energy dissipater structure also appeared to be in good condition.
